The warranty related to the operation reliability and safety of
the pumpset supplied is valid only if the equipment is operated
as per the designated parameters that have been mutually
agreed upon. The operating limits should not exceed from the
limits of Flow “Q” & Head “H” specified on the pump nameplate
and Voltage & Current in Amp specified on the motor nameplate.
2.5 Unauthorized site condition
The warranty of the pumpset will be in accordance with our
terms of Warranty Certificate. Our warranty will not apply if;
• The pump is used for handling the liquids other than those
specified / mutually agreed.

f) Specific gravity : 1.004
g) Hardness : 300, Max (Drinking water)
* ppm - parts per million
3.0 Preparation for Installation
3.1 Installation and operational accessories
The following accessories are necessary for installation and
commissioning of the pumpset :
• Extended cable (to be calculated as per 3.3.3) with
vulcanizing Rubber compound / Cushion compound and
electric insulation PVC tapes.
• Control panels with protection devices, Discharge Valve,
Pressure Gauge, Discharge pipes.
• Overload Trip unit, Water Level Guard,
• 2 Pairs of supporting or installation clamps for vertical
installation (for Horizontal installation supporting arrangement
as shown in Fig. 7)
(The motor is supplied with 3 core waterproof cable in standard
length of 3.25 meter).
3.2 Auxiliary equipment required for installation
and dismantling
For installing and removing the pumpset, reliable lifting device
(e.g. crane, chain pulley block) is required to handle the total
weight of the pumpset, riser pipe and an extended cable weight.
Please refer Table no 1 & 2 for the weight of pump and motor
respectively.Weight of pumpset for respective stages needs to
be calculated from Table no. 1.
